I'm still not clear.  Jeremy, have you seen examples which require the UNIX
credentials of the user accessing a tid to change from those supplied when
the tid was created?

What happens is when you cd onto the mapped drive in the
second (su'ed) window is that the redirector does a sessionsetupandX
call to get a new vuid, then it starts issuing SMB's with
the new vuid and old tid.

I first saw this about 5 years ago when I was at Vantive
watching an NT service log text onto a Samba mapped drive.


Buying an operating system without source is like buying
a self-assembly Space Shuttle with no instructions.
